Elon Musk breaks down climate change in the simplest way possible: Forget the extremes — not “climate change is fake” and not “Earth sinks in 5 years.” We’re pumping billions of tons of carbon from underground into the atmosphere. Obviously that will change the planet. The only question is: how fast? His estimate: not 5 years, not 500 years — but roughly 50. And the solution is simple: lean toward solar and batteries, and stop subsidizing oil.
